Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11722, here are decompositions:

  • 3 + 11719 = 11722
  • 5 + 11717 = 11722
  • 23 + 11699 = 11722
  • 41 + 11681 = 11722
  • 89 + 11633 = 11722
  • 101 + 11621 = 11722
  • 173 + 11549 = 11722
  • 233 + 11489 = 11722

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11722 first appears in π at position 353,563 of the decimal expansion (the 353,563ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
